1 This publication contains results from the WA Domestic Use of Water and Energy Survey, which was conducted throughout WA during the two weeks commencing Monday, 9 October 2006.

2 The survey was conducted as a supplement to the ABS Monthly Population Survey (MPS). The MPS is based on a multi-stage area sample of private dwellings and a list sample of special dwellings (hotels, motels, hospitals, prisons, short-stay caravan parks, etc.). Persons living in special dwellings were excluded from the scope of this survey. Information is obtained from the occupants of the selected dwellings by specially trained interviewers. For details of the design, scope and coverage of the MPS, users should refer to any recent edition of the ABS publication, Labour Force, Australia (cat. no. 6202.0) or the November 2002 edition of Information Paper: Labour Force Survey Sample Design (cat. no. 6269.0).

SCOPE

3 The WA Domestic Use of Water and Energy Survey was conducted on a subset of the full sample of private dwellings in WA that were included in the MPS. The survey covered all persons who were usual residents of private dwellings except:

members of non-Australian defence forces (and their dependents) stationed in Australia; and

persons living in sparsely settled areas of WA.

4 Information was collected by either face to face or telephone interview from one responsible adult per household. This adult answered questions on behalf of the household. Information was sought from approximately 3,630 households and data was obtained from approximately 98% of these households.

5 Data items collected on water using appliances and facilities, garden water use and swimming pools and outdoor spas were only collected for the Perth Metropolitan Statistical Region (SR). This was primarily due to data requirements being required for the Perth Metropolitan SR only, as well as questionnaire timing restraints. Remaining data items were collected for all households in WA.

COVERAGE

6 Coverage rules were applied to ensure that each person was associated with only one dwelling and hence had only one chance of selection in the survey.

EFFECTS OF ROUNDING

7 Estimates in this publication have been rounded and discrepancies may occur between sums of the component items and totals.
